Re: Remoting Collections leppie10-Jan-03 23:19 leppie 10-Jan-03 23:19  CollectionBAse is already Serializable, but maybe you need to declare an extra Serializable attribute to BArCollection WebBoxes - Yet another collapsable control, but it relies on a "graphics server" for dynamic pretty rounded corners, cool arrows and unlimited font support. Re: Remoting Collections billb211211-Jan-03 5:02 billb2112 11-Jan-03 5:02  Right above my class definition for BarCollection I have the [Serializable] attribute. Do I need to do something else? Give me one more medicated peaceful moment Re: Remoting Collections leppie11-Jan-03 5:11 leppie 11-Jan-03 5:11  Two suggestions 1. Have you tried passing it as a Array instead? 2. Add BarCollection into "container" class. Another thing to look for is the is what property caused the exception. That you should see before the stacktrace.

Re: Remoting Collections billb211211-Jan-03 5:49 billb2112 11-Jan-03 5:49  Thanks for the suggestions, however, I figured out the problem. Yes, BarData had to be marked as serializable, but even though BarCollection is derived from CollectionBase which is supposedly already serialized, I still have to add the [Serializable] attribute above that class as well. This is probably something that is glaringly obvious to anyone that knows anything about remoting ... but did I mention that this is the first day that I've tried it? Thanks for the replies! Give me one more medicated peaceful moment track bar int too double ? jtmtv1810-Jan-03 13:22 jtmtv18 10-Jan-03 13:22  whats the easyest way too adjust a track bar value from 1 too 100, into a double starting at 1.0 and working its way down to .0001 (for form opacity). i have it working with a huge switch, but i want a cleaner way to take the int value of say 100 too the double value of .0001 Re: track bar int too double ? David Stone10-Jan-03 13:39 David Stone 10-Jan-03 13:39  form.Opacity = (double)trackBar.Value / 1000000; I think that should work... I don't know whether it's just the light but I swear the database server gives me dirty looks everytime I wander past. -Chris Maunder Microsoft has reinvented the wheel, this time they made it round. -Peterchen on VS.NET Re: track bar int too double ? jtmtv1810-Jan-03 14:10 jtmtv18 10-Jan-03 14:10  thanks alot =) you just gave me back 200 lines of code i bet.. (it looks like that would work too me too...) im going too school as we speak to get my mcsd from a microsoft certified school.. for someone trying to become a windows app programmer (eventually games) is this a good start ? Re: track bar int too double ? David Stone11-Jan-03 5:57 David Stone 11-Jan-03 5:57  Actually, I would look at this article instead. It seems to work: http://www.codeproject.com/csharp/transparentwindowsincsharp.asp[^] I think Game Dev would be better done in C++.

Re: track bar int too double ? David Stone11-Jan-03 5:58 David Stone 11-Jan-03 5:58  You're right. I should have just done this: Form.Opacity = trackBar.Value / 100; I don't know whether it's just the light but I swear the database server gives me dirty looks everytime I wander past. -Chris Maunder Microsoft has reinvented the wheel, this time they made it round. -Peterchen on VS.NET Aborting updates in a DataTable stephen woolhead10-Jan-03 12:43 stephen woolhead 10-Jan-03 12:43  I am having a problem with aborting updates in a DataTable. I am hooked into the RowChanging Event and, as the docs say, throwing an exception to cause the update to abort. My problem is that the DataSet does not catch this exception and it bubbles all the way up to Main() which is a bit to late to do anything with. For this example I have a single form with a ListBox and a TextBox bound to a strongly typed DataSet. Anyone know how to handle this situation Thanks Sttephen. Re: Aborting updates in a DataTable jtmtv1810-Jan-03 13:28 jtmtv18 10-Jan-03 13:28  could you try butting your listbox on a seperate thread and abort the thread ? or maybe try putting the update in a while statement with a bool.... ie. it would be a pain too do it with the while statement though cause it would stay in it until the update tells it not too. i would try threads. while(turnOffUpdateflag==false) { ;//do my update } while(myThread.IsAlive == true) { ;//do update } Re: Aborting updates in a DataTable stephen woolhead10-Jan-03 13:57 stephen woolhead 10-Jan-03 13:57  <shudder> There as to be a better way! I am trying to validate the row when the list changes to a different row. This triggers the RowChanging event from the dataset. If I create the ListBox on another thread, when I abort the thread, surely I would lose the list box as well, and would have to recreate it and restore it to it's current state. 15 minute project has now managed to waste the best part of a day!! This looked so simple when I read the docs. LOL, should have known better by now! Stephen. Re: Aborting updates in a DataTable jtmtv1810-Jan-03 14:19 jtmtv18 10-Jan-03 14:19  i have a encryption program with the encryption method....the recursive file search method..all running on a string... when the user clicks stop..... it cancels the threads ..and the results that were found before the thread stopped are still in the list box... then when the user clicks the search button agian i tell the program too recreated the thread agian and it startes over any time you abort a thread you have to reintialize it ie make a private void just for your threads so you can call on then and get them reintialized when ever needed. i have never used a datagrid before (isnt that what you are using? cant remeber) but this has always worked for listboxes atleast. private void mylistboxThread() { Thread Update = new Thread(new ThreadStart(updatefunctions)) } private void updateFunctions() { //put your update code here. } Update.Start();//start thread Update.Abort();//abort thread jesse m Re: Aborting updates in a DataTable stephen woolhead10-Jan-03 15:42 stephen woolhead 10-Jan-03 15:42  But you are in control of starting the thread. What I want to do is in response to a users click on the listbox, which will be triggered from an incoming windows message (WM_MOUSE_DOWN or what ever) via the forms message loop that is running on the forms main thread, therefor my thread of execution would never make it onto my thread. Make sense? Stephen. Version number in deployment app Bog10-Jan-03 12:24 Bog 10-Jan-03 12:24  I'm making a deployment msi in VS.net, and I want to make the registry entry for the app be: HKEY_CURRENT_USER Software [Manufacturer] [ProductName] v[Version] myvariablehere what happens is, Manufacturer and ProductName get replaced as they should, but version just gets "v" without the version number after it. I also tried just "[Version]" but that didn't work either. Am I doing something wrong or can you not write the version into the name? "Outside of a dog, a book is Man’s best friend.

Okay I am trying to simulate the login screen that XP uses. Each opacid login box will be it's own form so i can control the opacity. The background form will be the MDI container for all the login forms. But I don't want the border ARRGGGG around the entire MDI container!!! Someone help.... Peace. Rubber band drawing in GDI+ Jojje10-Jan-03 7:53 Jojje 10-Jan-03 7:53  Wonder how to make a rubber band drawing with GDI+ in C#. Have used SetROP2( R2_XORPEN ) in C++ before, but that little function seemes to be gone in GDI+. Have tried to use interop with GDI, but there are quite a few functions that needs to imported and beeing lazy I want to know if there is a simpler way.

Find & Copy part of string Steve McLenithan10-Jan-03 6:52 Steve McLenithan 10-Jan-03 6:52  I have a string that will have a negative number as either the first 2 or 3 characters of it (including negative sign) immediately following this there is a colon : How can I copy everything before this initial colon into another variable. Reason for this: I need to perform some mathematical manipulation on this value but there is no way for me to get at it but via string because of the special characters.
